Structural Studies on Dimethyltin(IV) Carboxylates

In order to correlate (119)Sn Moessbauer parameters and structural data for trimethyltin(IV) derivatives, the mononuclear structure of bis(acetato)dimethyltin(IV) and bis(trifluoroacetato)dimethyltin(IV) were determined by single crystal X-ray diffraction. Crystals of Me2Sn(OOCCH3)2 are monoclinic, a=26.282(4), b=5.282(1), c=14.434(3) A, β=101.17(2)°, Z=8, space group C2/C, ant those of [Me2Sn(OOCCF3)2]n are monoclinic, a=8.444(1), b=17.689(1), c=15.368(1) A, β=93.013(9)°, Z=8, space group CC. The structures were solved by the Patterson method and were refined by full-matrix least-squares procedures to R=0.025 and 0.027 (Rw=0.023 and 0.030) for 2298 and 4182 reflections with I>=3σ(F**2), respectively.

Structural studies of diorganotin(IV) carboxylates. X-ray and NMR structures of Me2Sn(OAc)2 and a 7-coordinate tin anion, Me2Sn(OAc)3-NMe4 +·2CHCl3

The X-ray crystal and molecular structure of Me2Sn(OAc)2 is reported and compared with previous predictions based on other structural methods. The molecule is found to be monomeric and 6-coordinate at tin in the solid state. The Me-Sn-Me angle of 135.9 (2)° is in close agreement with the value predicted from solid-state and solution NMR studies. 119Sn NMR data are also reported for this compound. Me2Sn(OAc)2 crystallizes in the monoclinic space group C2/c (No. 15) with a = 12.712 (2) A?, b = 5.220 (1) A?, c = 14.365 (3) A?, β = 92.80 (1)°, and Z and 4; R refined to 0.022 and Rw to 0.029 for 1041 reflections. Me2Sn(OAc)2 reacts with Me4N+OAc- in CHCl3 solution to give a quantitative yield of Me2Sn(OAc)3-NMe4+. Me2Sn(OAc)3-NMe4+ crystallizes with two molecules of CHCl3 in orthorhombic space group Pbca (No. 61) with a = 16.717 (2) A?, b = 17.475 (2) A?, c = 18.242 (3) A?, and Z = 8; R refined to 0.059 and Rw to 0.047 for 1723 reflections. Me2Sn(OAc)3-NMe4+ is 7-coordinate at tin and has a Me-Sn-Me angle of 165.8°. CHCl3 in the crystal lattice is weakly hydrogen bonded to several oxygens of the tin complex. Solution 1H, 13C, and 119Sn and solid-state 13C NMR studies provide evidence for retention of the high coordination number in solution and for rapid, reversible acetate exchange in solution.

PROTOLYSES OF (CH3)3SnM(CH3)3 (M = Sn, Ge, SI, C)

Product and kinetic studies on the reactions of hydrogen chloride in methanol solution with the substrates (CH3)3SnM(CH3)3 (M = Sn; Ge and Si) show that both Sn-M and Sn-CH3 cleavage reactions occur, at similar rates, and are followed by other reactions g
